DISPLAYlNG ADVERTISEMENTS ON CARS.

SPECIFICATION forming part of Letters Patent No. 364,279, dated June 7, 1887.

Application iiled January 28, 1887. Serial No. 225,762 l (No model.) Patented in England March .22. 1986, No. 3,997,

To @ZZ whom t may concern:

Beitknown that we, GHARLns SoMnRvrLLE NELsoN and WILLIAM NEWBY CoLAM, subjects ofthe Queen of Great Britain, residing in London, inthe county of Middlesex, England, haveinvcnted certain new and useful Improvements in Displaying Advertisements on Tram- Gars and Similar Vehicles, (for which we have obtained a patentin Great Britain, No. 3,997,

1c bearing date March 22, 1886,) of which the following is a specification.

Our invention relates to a device for displaying advertisements on tranrcars, omnibuses, and similar vehicles; and the objects of I5 our invention are, first, to render the advertisements more attractive; second, to increase the area availablev for advertising purposes, and, therefore, thirdly, to increase the value of these vehicles as advertising mediums. XVe

attain these objects by mechanism illustrated in the accompanying drawings, in which Figure 1, Sheet No. l, isalongitudinal section, and Fig. 2, Sheet'No. 1, is a transverse section, of a tramcar, showing the general arrangement of the mechanism. Fig. 3, Sheet N o. 2, is asectional View, on an enlarged scale, showingthe end of one of the advertisingrollers and one of the bearings supporting it. Fig. 4, Sheet No. 2, is a sectional View, on an 3o enlarged scale, showing the mechanism for Voperating the rollers. Fig. 5, Sheet No. 2, is a transverse section of a roller having six sides. Figs. 6, 7, S, and 9, Sheet N o. 8, are views, on an enlarged scale, showing the mechanism for transmitting the motion necessary to operate the rollers from one of the axles of a car.

Similarletters refer to similar parts th roughout the several views. Y p

The rollers A A,&c., which are made with four or more sides to receive the advertisements, are mounted on a continuous axle, B,

on each side of the vehicle, the rollers being in short lengths to coincide with the panels of 4 5 the car. The axles B B are mounted in suitable bearings, C G, dre., iixed to the frame of the vehicle. The rollers are inclosed in cases l) D, formed across the angles formed by the junctions of the sides and roof of the car 5o or vehicle, suitable openings being provided .illustrated by Fig. 4.

to allow one of the faces ot' each roller to be visible at one andthe same time. Each axle carrying the advertising-rollers is caused t0 rotate by the following mechanism:

On one end of each of the axles B B we iix a ratchet-wheel, b, and in convenient prox imity thereto we mount loosely on the axle an arm, b', carrying a pawl, b2, engaging with the teethI of the ratchet-wheel b, aspring, b, being provided to keep it engaged therewith. Connected with the arm b is a cord or chain, b", which receives an intermittent reciprocating motion from mechanism to be hereinafter described, the cord or chain being carried down to the floor ofthe car by suitable guides.

W'hen the cord or chain I1 is pulled down, the pawl b2 on the arm b' rides over the teeth of the ratchet-wheel I), and as it is pulled up again by the spring b5 the pawl engages with the teeth of the ratchet-wheel I) and moves the axle suiciently to bring the next side or face of the rollers opposite to the openings d d, &c., in cases D D, &c.,whieh inclose them. It may sometimes be more convenient to effect the rotation ofthe axle carrying the ad vertisingroll- 7r ers by the downward pull ofthe cord or chain instead of by the converse movement hereinbefore described, in which case the pawl and ratchet-wheel are arranged accordingly.

We do not bind ourselves to the use of rollers having four sides, as shown by Figs. `1, 2, 3, and 4, as rollers with six, eight, or more sides may be used. A roller with six sides is It will be obvious that the number of iat sides bi, Ste., eut or formed on the boss of the ratchet-wheel b must coincide with the number of sides on the rollers A A, 85e. The arms b b', through the cords or chains b b, receive their intermittent reciprocating mot-ion through the following mechanism: Under one of the seats' of the car is mounted, in suitable bearings, E E, alay-axle, F, which carries a large pulley, G, the periphery of which is `in frictional contact with one of theaxles X of the car, or with a small pulley fixed thereto. By this arrangement a consid erable reduction of speed is obtained. To attain sufficient driving contact, the bearings E E are mounted in horn-plates E E', so that the whole weight of the pulley G bears on the IOO axle X, and, if necessary, the periphery of the pulley, or that part of the axle with which. it is in contact, may be covered with leather, rubber, or analogous material.

On the axle Fis fixed a pulley, II, connected with a similar pulley,J, carried by an axle, Ii, mounted in bearings 7c k, so that the ends of the axle are as nearly under the cords or chains D* b as possible. l

On each end ofthe axle K is lixed or formed a projecting arm, it', with a small roller, k2, mounted on a pin at its free end. In suitable brackets, LL, either forming part of thebearing-brackets for the axle K or mounted independenti y on the under frame of the car, are pivoted levers ZZ. The ends of these ievers on one side of their fulcrums are con nected to the cords or chains b b, and their opposite ends engage with the rollersk2 la, carried on the ends of the arms k k, thus im parting an intermittent reciprocating motion to the arms b through the cords or chains b'L Za, the springs b3 b5 insuring the contact between the levers andthe rollers.

It will `be understood that the gear hereinbefore described is equally effective for operating the advertising-rollers whichever way the car is traveling, and permits of the axles carrying the rollers being geared down to almost any extent. In practice we find that thirty seconds is a convenient period foreach side of the rollers to remain stationary and exposed Vto view, though it will be obvious that this period may be lengthened or shortened by varying the proportions ofthe motion-wheels- We are aware that endless revolving -or traveling bands or aprons have already been used on tram-cars and similar vehicles for displaying advertisements, and we are also aware that revolving` rollers have been used on advertising-1nachines and other vehicles used solely for the purpose of advertising. 7e therefore do not claim the use of revolving rollers, broadly; but,

I-Iaving now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that what we claim is- 1. In a tram-car or other similar vehicle for the conveyance of passengers, the combination, with thecar-body, of the polysided rollers journaled in the angle formed by the car roof and side, and the casing-strips having an opening between them, to allow but one side of each roller to be visible at one and the same time, substantially as set forth.

2. In atram-car or other similar vehicle for the conveyance of passengers, the combination, with the body ofthe vehicle, of the longitudinally-mounted polysided rollersjournaled in the angle formed by the car roof and side, the casing-strips having an opening between them, so that only one side of each roller is visible to the occupants of the'car at the same instant, and the mechanism for imparting au intermittent rotating motion to the rollers from the continuous rotating motion of one of the axles of the car, all arranged and operating in the manner hereinbet'ore set forth.

3. The combination of the polysidcd advertisement-rollers, the ratchet-wheel secured on the roller-spindle, the arm provided with a pawl for turning theratcliet, a spring for turningthe arm in one direction, a cord secured to the arm for turning it in the reverse direction, a rocking lever pivoted to the car-frame and secu red to the cord, the projecting arm k', having roller k, for operating said lever and secured upon axle K, the friction-wheel journaled in sliding plates and bearing on the caraxle, and a driving-cord connecting the axle K with the said friction -wheel, substantially as and for the purpose set forth.

4. The combination of the ear-trame mounted upon revoluble axles, a friction wheel jou rnaled in sliding plates and bearing upon one vof the said axles, the projecting arm 7;', hav- CHARLES SOMERVILLE NELSON, WlhlilAM NEWBY COLAM.
